Spec File

Goal

Build the evidence accumulation system that tracks all evidence (from debates, citations,
usage, replication) about each artifact and maintains a structured evidence profile.

Every artifact should have a queryable evidence profile that answers:

How many debates have examined this artifact? What were the outcomes?
How many other artifacts cite, link to, or embed this one?
Has this artifact been replicated or contradicted by independent work?
What is the trend — is evidence for this artifact growing or shrinking?

Acceptance Criteria

☐ artifact_evidence_profile view or materialized query that aggregates:

- Debate count and outcomes (supports/contradicts/neutral)
- Incoming link count by type (cites, derives_from, supports, contradicts, embeds)
- Outgoing link count by type
- Version count and stability
- Quality score trajectory (last 5 updates)

☐ compute_evidence_profile(artifact_id) function in artifact_registry.py

☐ Evidence profile feeds into propagate_quality() — more evidence = more certain score

☐ Evidence balance metric: (supporting - contradicting) / total evidence

☐ API: GET /api/artifact/{id}/evidence-profile — structured evidence summary

☐ Profile data shown on artifact detail pages

Dependencies

agr-ad-01-TARG — Debates must be targetable to produce artifact-specific evidence

Dependents

agr-ad-03-USAGE — Usage signals are one input to the evidence profile
agr-ad-05-PROF — Dashboard visualizes evidence profiles

Task: Implement artifact evidence accumulation system
Status: Completed

Implementation Details

compute_evidence_profile(artifact_id) — added to scidex/atlas/artifact_registry.py:

- Aggregates debate outcomes from artifact_debates table (supports/contradicts/neutral)
- Counts incoming links by type from artifact_links
- Counts outgoing links by type
- Tracks version count via parent_version_id relationships
- Pulls quality score trajectory from artifacts_history
- Computes evidence balance: (supports - contradicts) / total_evidence
- Computes evidence certainty: min(1.0, total_incoming / 20)
- Classifies artifacts: is_well_supported, is_controversial, is_foundational

propagate_quality() enhancement — updated to use compute_evidence_profile:

- Blend ratio now modulated by evidence certainty
- Low evidence (0.2) → conservative 50/50 upstream/current blend
- High evidence (1.0) → confident 85/15 upstream/current blend

API endpoint — GET /api/artifacts/{id}/evidence-profile in api.py:

- Returns structured evidence profile JSON
- 404 if artifact not found

Artifact detail page — evidence profile section added to /artifact/{id} HTML:

- Evidence balance, certainty, debate count, in/out link counts
- Support/contradict/neutral breakdown
- Classification badges (Well Supported / Controversial / Foundational)
- Link to full JSON evidence profile

Test file fix — scripts/tests/test_evidence_profile.py:

- Fixed import path from artifact_registry to scidex.atlas.artifact_registry

Files Changed

scidex/atlas/artifact_registry.py — added compute_evidence_profile(), modified propagate_quality()
api.py — added evidence profile API route, added to artifact detail HTML
scripts/tests/test_evidence_profile.py — fixed import path
